IOTA-255A high-phenyl modified high-temperature resistant silicone oil features an ultra-wide operating temperature range from -70℃ to 320℃. It addresses the pain points of ordinary phenyl silicone oil such as insufficient heat resistance and poor thermal stability. It can be used as high-temperature heat carrier and base oil for lubricating grease, meeting industrial requirements of insulation, damping, shock resistance and other applications.



In industrial sectors including aerospace, electronics and precision equipment, many devices operate under alternating extreme low and high temperature environments. Conventional phenyl silicone oil tends to oxidize easily at high temperatures and lose fluidity at low temperatures. Its usable temperature range is limited, and performance degradation often occurs after long-term operation, which undermines the stability of the whole set of equipment. Engineers frequently encounter difficulties in silicone oil selection: insufficient thermal stability and weak oxidation resistance, failing to cope with both high and low temperature working conditions simultaneously.

IOTA-255A is modified phenyl silicone oil with high phenyl content. Compared with standard phenyl silicone oil, it delivers improved high-temperature resistance, with operating temperature ranging from -70℃ to 320℃. It maintains stable physical and chemical properties under low-temperature conditions and prolonged high-temperature service. The product boasts excellent thermal stability and oxidation resistance, together with favorable lubricity, radiation resistance and water stability to withstand harsh working environments.

In practical applications, IOTA-255A has versatile uses. It can serve as high-temperature heat carrier for insulation, lubrication, damping, shock resistance and dust-proof scenarios. It also works as base stock for high-temperature lubricating oil and grease. In precision instruments and special equipment fields, this modified phenyl silicone oil can keep functioning steadily under large temperature fluctuations, radiation exposure and humid conditions, cutting equipment maintenance costs caused by medium failure.

The key to organic silicone material selection lies in matching working temperature, environmental medium and long-term stability requirements. Restricted by molecular structure, traditional phenyl silicone oil gradually ages under high temperature and cannot sustain long continuous high-temperature operation. With molecular structure optimized via phenyl modification, IOTA-255A expands the applicable temperature window. It avoids solidification at low temperature and deterioration under high heat.

For industrial customers, stable materials ensure continuous production and lower equipment failure rates. As a high-phenyl modified silicone oil, IOTA-255A provides a new material option for rigorous high-low temperature conditions. It meets demands for special lubrication, heat transfer and insulation protection, helping various equipment run reliably under complex thermal environments.
